Description

Die Erfindung betrifft ein Profiliergerüst für eine Rollumformanlage nach dem Oberbegriff des Anspruchs 1. Demnach umfasst das Profiliergerüst ein Gestell mit einer ersten Formrolle und einer zweiten Formrolle, zwischen denen ein umzuformendes Werkstoffband hindurchgeführt wird, um es in ein Profil umzuformen, oder ein entsprechendes Profil hindurchgeführt wird, um es weiter umzuformen. Hierfür kommen alle umformbaren Werkstoffe in Betracht, insbesondere Metallbleche. Die Formrollen können angetrieben oder auch freilaufend sein. Vorliegend sitzt jedoch mindestens eine der beiden Formrollen auf einer Welle, insbesondere einer Antriebswelle, welche ihrerseits so in einer Exzenterbuchse gelagert ist, dass ein Verdrehen der Exzenterbuchse eine achsparallele, laterale Verschiebung der Welle relativ zum Gestell bewirkt, um den Abstand der beiden Formrollen zueinander an unterschiedliche Werkstoffband-Dicken anzupassen.The invention relates to a Profiliergerüst for a Rollumformanlage according to the preamble of claim 1. Accordingly, the Profiliergerüst comprises a frame with a first forming roller and a second forming roller, between which a material strip to be formed is passed to reshape it into a profile, or passed a corresponding profile is going to reshape it. For this purpose, all formable materials into consideration, especially metal sheets. The form rollers can be driven or free-running. In the present case, however, at least one of the two forming rollers is seated on a shaft, in particular a drive shaft, which in turn is mounted in an eccentric bush so that a rotation of the eccentric bushing causes an axially parallel, lateral displacement of the shaft relative to the frame, by the distance of the two forming rollers to each other adapt different material strip thicknesses.

Rollumformanlagen, in denen derartige Profiliergerüste verwendet werden, bestehen im Wesentlichen aus einer Vielzahl von solchen Profiliergerüsten in Linie, durch die hindurch das in ein Profil umzuformende Werkstoffband geführt und sukzessive in das gewünschte Endprofil umgeformt wird. In jedem Umformschritt durchläuft das Werkstoffband jeweils mindestens zwei zusammenwirkende Formrollen, die die Kräfte zum Umformen des Werkstoffbandes auf dieses übertragen. Der Abstand zwischen diesen mindestens zwei zusammenwirkenden Formrollen muss hierbei an die Dicke des Werkstoffbandes angepasst sein.Roll forming plants in which such Profiliergerüste be used, consisting essentially of a variety of such Profiliergerüsten in line, passed through which the reshaped into a profile material band and successively transformed into the desired final profile. In each forming step, the material strip in each case passes through at least two cooperating forming rollers, which transmit the forces for forming the material strip on this. The distance between these at least two cooperating shaping rollers must be adapted to the thickness of the material band.

Um nun Werkstoffbänder mit unterschiedlichen Dicken in ein und derselben Rollumformanlage profilieren zu können, müssen die Profiliergerüste mit solcherart verstellbaren Formrollen versehen sein, dass der Abstand zwischen den zusammenwirkenden Formrollen veränderbar und der veränderten Werkstoffband-Dicke anpassbar ist. Da zum Umformen des Werkstoffbandes allerdings hohe Kräfte wirken müssen, die insbesondere in Richtung der Verbindungsstrecke zwischen den Formrollenachsen der zusammenwirkenden Formrollen wirken, ist es schwierig, eine solche Verstellung zu realisieren. Denn der Verstellmechanismus muss den hohen Umformkräften standhalten.In order to be able to profile material strips with different thicknesses in one and the same Rollumformanlage, the Profiliergerüste must be provided with such adjustable mold rollers that the distance between the cooperating mold rollers changeable and the changed material thickness band is adaptable. However, since high forces must act to deform the material strip, which act in particular in the direction of the connecting path between the forming roller axes of the cooperating shaping rollers, it is difficult to realize such an adjustment. Because the adjustment mechanism must withstand the high forming forces.

Aus der EP 0 712 674 A1 ist ein Profiliergerüst für eine Rollumformanlage bekannt geworden, bei dem zwei übereinander angeordnete Formrollen auf je einer Antriebswelle sitzen und mit diesen in einem Gestell gelagert sind. Um den Abstand der beiden Formrollen zueinander unterschiedlichen Werkstoffband-Dicken anzupassen, ist die Antriebswelle einer der beiden Formrollen in einer Exzenterbuchse gelagert. Ein Verdrehen dieser Exzenterbuchse bewirkt eine achsparallele, laterale Verschiebung der Welle bezüglich des Gerüsts, so dass sich der Abstand zwischen den beiden Formrollen verändert. Die Exzenterbuchse selbst kann die hohen, zwischen dem Werkstoffband und den Formrollen wirkenden Kräfte problemlos aufnehmen und in das Gestell einleiten, während die Gegenkraft, die ein Verdrehen der Exzenterbuchse bewirken will, mit relativ kleinen Haltekräften neutralisiert werden kann.From the EP 0 712 674 A1 is a Profiliergerüst known for a Rollumformanlage, in which two superposed form roles sitting on each drive shaft and are stored with them in a frame. In order to adjust the distance between the two forming rollers to each other different material strip thicknesses, the drive shaft of one of the two forming rollers is mounted in an eccentric bushing. A rotation of this eccentric bush causes an axis-parallel, lateral displacement of the shaft with respect to the framework, so that the distance between the two shaping rollers changes. The eccentric bush itself can easily absorb the high forces acting between the material strip and the forming rollers and initiate them into the frame, while the counterforce, which aims to effect a rotation of the eccentric bushing, can be neutralized with relatively small holding forces.

Die Rotationsbewegung an der Exzenterbuchse, die für eine laterale, achsparallele Verschiebung der Formrolle notwendig ist, führt allerdings naturgemäß zu einer Verdrehung der Formrolle um die Wellenachse bzw. um die Achse der Exzenterbuchse. Solange die Formrolle achsparallel mit der Welle und der Exzenterbuchse angeordnet ist, ist diese Verdrehung unproblematisch, denn die Formrolle ist dann gerade um diese Achse rotationssymmetrisch ausgebildet. Problematisch wird die bekannte exzentrische Verstellung der Formrollen jedoch dann, wenn es sich beim Profiliergerüst um eine Schrägrolleneinheit handelt, also wenigstens eine der beiden Formrollen eine Rotationsachse aufweist, die gegenüber der Achse der zugeordneten und in der Exzenterbuchse gelagerten Welle abgewinkelt verläuft. Denn wenn dann die Exzenterbuchse verdreht wird, bewegt sich die Achse der abgewinkelt angeordneten Formrolle entlang einer Kegelfläche aus der Arbeitsposition heraus.However, the rotational movement on the eccentric bush, which is necessary for a lateral, axially parallel displacement of the forming roller, naturally leads to a rotation of the forming roller about the shaft axis or about the axis of the eccentric bushing. As long as the forming roller is arranged axially parallel to the shaft and the eccentric bushing, this rotation is not a problem, because the form roller is then designed to be rotationally symmetrical about this axis. However, the known eccentric adjustment of the forming rollers becomes problematic when the profiling stand is a helical roller unit, that is to say that at least one of the two forming rollers has an axis of rotation which is angled relative to the axis of the associated shaft mounted in the eccentric bushing. Because if then the eccentric bushing twisted is moved, the axis of the angled arranged form roller along a conical surface moves out of the working position.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Profiliergerüst mit exzentrischer Verstellung des Abstandes der Formrollen der eingangs beschriebenen Art so zu modifizieren, dass die exzentrische Verstellung des Abstandes der Formrollen auch dann einsetzbar ist, wenn die exzentrisch zu verstellende Formrolle gegenüber ihrer Welle abgewinkelt ist, es sich beim Profiliergerüst also um eine Schrägrolleneinheit handelt.The present invention is therefore the object of a profiling with eccentric adjustment of the distance of the forming rollers of the type described above to modify so that the eccentric adjustment of the distance of the forming rollers is also used when the eccentric to be adjusted form roller is angled relative to its shaft That is, it is the Profiliergerüst so a Schrägrolleneinheit.

Gelöst ist diese Aufgabe durch ein Profiliergerüst mit den Merkmalen des Anspruchs 1. Bevorzugte Ausgestaltungen und Weiterbildungen des erfindungsgemäßen Profiliergerüsts sind in den Ansprüchen 2 bis 14 niedergelegt.This object is achieved by a Profiliergerüst with the features of claim 1. Preferred embodiments and further developments of the invention Profiliergerüsts are laid down in claims 2 to 14.

Das aus dem Stand der Technik bekannte Profiliergerüst mit exzentrischer Verstellung des Formrollenabstands wird nach der vorliegenden Erfindung also dadurch modifiziert, dass die der Exzenterbuchse zugeordnete Formrolle an einer Trägerhülse gelagert ist, welche drehbar in der Exzenterbuchse sitzt und lateral verschieblich am Gestell angebracht ist, sich also wegen der lediglich lateral verschieblichen Anbringung am ortsfesten Gestell nicht mit der Exzenterbuchse mitdrehen kann. Dementsprechend verdreht sich auch die verstellbare Formrolle bzw. deren Achse beim Verdrehen der Exzenterbuchse nicht.The Profiliergerüst known from the prior art with eccentric adjustment of the mold roller spacing is therefore modified according to the present invention in that the eccentric bush associated with the form roller is mounted on a support sleeve which is rotatably mounted in the eccentric bush and laterally displaceable mounted on the frame, so because of the only laterally displaceable attachment to the stationary frame can not rotate with the eccentric bushing. Accordingly, the adjustable form roller or its axis does not twist during rotation of the eccentric bush.

In bevorzugter Weise ist die Trägerhülse über mindestens zwei drehbar im Gestell und in der Trägerhülse sitzende Exzenterbolzen lateral verschiebbar am Gestell angebracht, wobei diese Exzenterbolzen vorzugsweise dasselbe Exzentermaß wie die Exzenterbuchse aufweisen. Wird also die Exzenterbuchse verdreht, versucht die Trägerhülse sich sowohl mitzudrehen, als auch sich zwangsweise achsparallel lateral zu verschieben. Da über die Exzenterbolzen jedoch eine Verbindung mit dem ortsfesten Gestell besteht und mindestens zwei Exzenterbolzen vorhanden sind, wird die Trägerhülse an einer Rotationsbewegung gehindert. Die laterale Verschiebebewegung ist jedoch möglich, da die Exzenterbolzen sowohl in der Trägerhülse als auch im Gestell drehbar sitzen und der lateralen Bewegung der Trägerhülse durch eine Drehung ausweichen, die der Verdrehung der Exzenterhülse entspricht, soweit ein identisches Exzentermaß gewählt worden ist.Preferably, the support sleeve is laterally slidably mounted on the frame via at least two rotatably seated in the frame and in the support sleeve eccentric, said eccentric preferably have the same eccentric dimension as the eccentric bushing. Thus, if the eccentric bushing is twisted, the carrier sleeve will try to rotate as well as forcefully move laterally parallel to the axis. However, since there is a connection with the stationary frame via the eccentric pin and at least two eccentric bolts are present, the support sleeve is prevented from rotating. However, the lateral displacement movement is possible because the eccentric pins are rotatable both in the carrier sleeve and in the frame and avoid the lateral movement of the carrier sleeve by a rotation, which corresponds to the rotation of the eccentric sleeve, as far as an identical Exzentermaß has been selected.

Grundsätzlich kann dieses erwünschte gelenkige Verhalten der Trägerhülse auch über eine Gelenkanordnung oder eine entsprechend ausgestaltete Kulissenführung von nicht exzentrischen Haltebolzen erzielt werden. Wichtig ist im Rahmen der Erfindung jeweils nur, dass die Trägerhülse an einer Verdrehung gegenüber dem Gestell gehindert wird, während eine laterale Verschiebung entsprechend der lateralen Verschiebung der Achse der verdrehten Exzenterbuchse möglich ist. Gleichwohl ist die Lösung über Exzenterbolzen besonders bevorzugt.In principle, this desired articulated behavior of the carrier sleeve can also be achieved by means of a joint arrangement or a correspondingly designed link guide of non-eccentric retaining bolts. It is important within the scope of the invention in each case only that the support sleeve is prevented from rotating relative to the frame, while a lateral displacement corresponding to the lateral displacement of the axis of the rotated eccentric bushing is possible. Nevertheless, the solution over eccentric bolts is particularly preferred.

Wie sich aus der oben beschriebenen, der Erfindung zugrunde liegenden Aufgabe ergibt, wird die Erfindung bevorzugterweise bei Profiliergerüsten eingesetzt, die mindestens eine Formrolle aufweisen, deren Rotationsachse gegenüber der über die Exzenterbuchse verstellbaren Achse der zugeordneten Welle abgewinkelt verläuft, also eine Schrägrolleneinheit vorliegt; insbesondere wenn ein an der Trägerhülse befestigtes Gehäuse vorgesehen ist, an welchem die der Exzenterbuchse zugeordnete Formrolle gelagert ist, und welches eine Umlenkung zur Übertragung des Drehmoments an der Welle auf die Formrolle beinhaltet, beispielsweise ein Kardangelenk oder Kegelzahnräder.As is apparent from the above-described, the invention underlying object, the invention is preferably used in Profiliergerüsten, which have at least one form of role whose axis of rotation is angled relative to the adjustable over the eccentric bush axis of the associated shaft, so there is a Schrägrolleneinheit; in particular if a housing fastened to the carrier sleeve is provided, on which the forming roller assigned to the eccentric bushing is mounted, and which includes a deflection for transmitting the torque to the shaft on the forming roller, for example a universal joint or bevel gears.

Besondere Vorteile ergeben sich, wenn die Exzenterbuchse und/oder die Trägerhülse des erfindungsgemäßen Profiliergerüsts gegenüber dem Gestell axial verstellbar ausgebildet sind. Denn gerade bei Schrägrolleneinheiten, jedoch auch bei der Verwendung von achsparallelen Formrollen genügt es meist nicht, nur den Abstand der beiden Achsen der zusammenwirkenden Formrollen zu vergrößern, um ein dickeres Werkstoffband bzw. ein dickeres Profil durchführen zu können, sondern es muss gleichzeitig auch ein axialer Versatz zweier zusammenwirkender Formrollen vergrößert bzw. verkleinert werden. Bei Schrägrolleneinheiten ist dies unmittelbar einleuchtend; bei Formrollenpaaren mit parallelen Achsen ist ein axialer Versatz dann notwendig, wenn das hindurchgeführte Metallband ein Profil aufweist, bzw. aufweisen soll, dessen Querschnitt nicht nur horizontal verläuft, sondern auch eine vertikale Komponente hat.Particular advantages arise when the eccentric bushing and / or the carrier sleeve of the profiling stand according to the invention are formed axially adjustable relative to the frame. For just with Schrägrolleneinheiten, but also with the use of paraxial form rollers, it is usually not enough to increase only the distance between the two axes of the cooperating form rollers to perform a thicker material band or a thicker profile, but it must also be an axial Offset of two co-acting form rollers can be increased or decreased. For helical roller units this is immediately obvious; In the case of pairs of forming rollers with parallel axes, an axial offset is necessary if the metal strip passed through has or should have a profile whose cross-section not only extends horizontally but also has a vertical component.

Besonders bevorzugt ist es hierbei, wenn die axiale Verstellung der Exzenterbuchse und/oder der Trägerhülse unabhängig von der Verdrehung der Exzenterbuchse ist. Denn dann kann nicht nur eine synchrone Verstellung des Achsabstands und des axialen Versatzes erfolgen, sondern auch eine asynchrone Verstellung.It is particularly preferred in this case if the axial adjustment of the eccentric bush and / or the carrier sleeve is independent of the rotation of the eccentric bushing. Because then not only a synchronous adjustment of the axial distance and the axial offset can be done, but also an asynchronous adjustment.

Zur axialen Verstellung der Exzenterbuchse kann diese ein zu ihrer Außenfläche konzentrisches Gewinde aufweisen, auf welchem ein Zahnrad mit Innengewinde läuft, welches seinerseits relativ zum Gestell axial nicht verschiebbar gelagert ist. Hierzu kann ein Stellantrieb mit einem weiteren Zahnrad vorgesehen sein, das mit dem eben genannten Zahnrad mit Innengewinde kämmt.For axial adjustment of the eccentric bush, this can have a concentric to its outer surface thread on which a gear wheel with internal thread runs, which in turn is mounted axially non-displaceable relative to the frame. For this purpose, an actuator can be provided with a further gear, which meshes with the aforementioned gear with internal thread.

Zur Verdrehung der Exzenterbuchse kann an dieser ein Schwenkhebel angebracht sein, dessen Hebelwirkung die Gegenkraft der Umformung, die ein Verdrehen der Exzenterbuchse bewirken will, nochmals verringert. Mehrere erfindungsgemäß ausgestaltete Profiliergerüste in einer Rollumformanlage können dann solcherart synchronisiert werden, dass ein Gestänge die Schwenkhebel aller Profiliergerüste untereinander verbindet.To rotate the eccentric bush may be mounted on this a pivot lever whose leverage reduces the counterforce of the deformation, which aims to cause a rotation of the eccentric bushing again. Several according to the invention configured Profiliergerüste in a Rollumformanlage can then be synchronized such that a linkage interconnects the pivoting lever of all Profiliergerüste.

Der ersten und zweiten Formrolle kann mindestens eine Seitenrolle, insbesondere eine mitlaufende Seitenrolle zugeordnet sein, vor allem wenn es sich beim erfindungsgemäßen Profiliergerüst um eine Schrägrolleneinheit handelt.At least one side roll, in particular a running side roll, can be associated with the first and second forming rolls, especially if the profiling frame according to the invention is a skew roll unit.

Die Exzenterbuchse ist vorzugsweise gleitgelagert, während die Exzenterbolzen wälzgelagert sind. Hierdurch verringert sich der Widerstand der Exzenterbolzen gegen eine erwünschte laterale Verschiebung der Wellenachse, während die Exzenterbuchse nicht zu leichtgängig gelagert ist, um eine Selbsthemmung der Verdrehneigung aufgrund der Gegenkraft der Umformkräfte an den Formrollen zu erreichen. Diese Selbsthemmung kann so stark ausgeprägt sein, dass keine externen Haltekräfte an der Exzenterbuchse angreifen müssen.The eccentric bushing is preferably slidably mounted while the eccentric bolts are roller-mounted. This reduces the resistance of the eccentric bolt against a desired lateral displacement of the shaft axis, while the eccentric bushing is not stored too smoothly to achieve a self-locking the Verdrehneigung due to the opposing force of the forming forces on the forming rollers. This self-locking can be so pronounced that no external holding forces must act on the eccentric bushing.

Als bevorzugter Winkelbereich für die Verdrehung der Exzenterbuchse hat sich ein Winkelbereich von plus 30 Grad bis minus 30 Grad, insgesamt also 60 Winkelgrade herausgestellt.As the preferred angular range for the rotation of the eccentric bush, an angle range of plus 30 degrees to minus 30 degrees, a total of 60 degrees has been found.

Figur 1 zeigt ein erfindungsgemäß aufgebautes Profiliergerüst 10 in einer seitlichen Schnittdarstellung. Dieses umfasst zwei miteinander zusammenwirkende, angetriebene Formrollen 11 und 12, zwischen denen ein bereits vorprofiliertes Werkstoffband 31 (Figur 10) hindurchgeführt wird, und mit denen weiterhin eine freilaufende Seitenrolle 14 zusammenwirkt. Das Profiliergerüst 10 umfasst daneben ein weiteres Formrollenpaar 13 und 12 sowie eine mit diesen beiden zusammenwirkende freilaufende Seitenrolle 15.FIG. 1 shows a profiling stand 10 constructed according to the invention in a lateral sectional representation. This comprises two cooperating, driven forming rollers 11 and 12, between which an already pre-profiled material strip 31 (Figure 10) is passed, and with which further a free-running side roller 14 cooperates. The Profiliergerüst 10 includes next to another form roller pair 13 and 12 and a cooperating with these two free-running side roller 15th

Das Profiliergerüst 10 umfasst ferner ein Gestell 16, in dem Antriebswellen 32, 33 und 34 für die Formrollen 11, 12 und 13 gelagert sind. Das hier vorliegende Profiliergerüst 10 ist als Schrägrolleneinheit ausgestaltet, d. h. die Formrollen 11 und 13 besitzen Rotationsachsen 35 und 36, die gegenüber den Achsen der zugehörigen Antriebswellen 32 und 34 abgewinkelt sind. Dementsprechend ist jeweils ein Gehäuse 17, 18 vorhanden, an dem die Formrollen 11, 13 gelagert sind, und welche die Umlenkung zur Übertragung des Drehmoments von den Antriebswellen 32, 34 auf die Formrollen 11, 13, vorliegend ein (nicht dargestelltes) Kegelradgetriebe, beinhalten.The profiling stand 10 further comprises a frame 16 in which drive shafts 32, 33 and 34 for the forming rollers 11, 12 and 13 are mounted. The present profiling stand 10 is designed as a skew roller unit, ie the forming rollers 11 and 13 have rotation axes 35 and 36, which are angled relative to the axes of the associated drive shafts 32 and 34. Accordingly, in each case a housing 17, 18 is provided, on which the forming rollers 11, 13 are mounted are, and which the deflection for transmitting the torque from the drive shafts 32, 34 on the forming rollers 11, 13, in this case a (not shown) bevel gear, include.

Um nun den Abstand zwischen den Formrollen 11 und 12 in y-Richtung zu verstellen, um diesen an eine andere Dicke des Werkstoffbandes 31 anzupassen, ist die Antriebswelle 32 in einer Exzenterbuchse 20 gelagert, welche über einen Schwenkhebel 25 verdreht werden kann. Eine Verdrehung der Exzenterbuchse 20 bewirkt eine laterale, achsparallele Verschiebung der Antriebswelle 32 und des Gehäuses 17, so dass sich der Abstand zwischen den Formrollen 11 und 12 in y-Richtung verändert.In order to adjust the distance between the forming rollers 11 and 12 in the y-direction in order to adapt this to a different thickness of the material strip 31, the drive shaft 32 is mounted in an eccentric bushing 20, which can be rotated by a pivoting lever 25. A rotation of the eccentric bush 20 causes a lateral, axially parallel displacement of the drive shaft 32 and the housing 17, so that the distance between the forming rollers 11 and 12 changes in the y-direction.

Um nun zu verhindern, dass das Gehäuse 17 sich beim Verdrehen der Exzenterbuchse 20 mit dieser mitdreht und hierdurch die Rotationsachse 35 der Formrolle 11 entlang einer Kegelfläche aus der Arbeitsposition herauswandert, ist in die Exzenterbuchse.20 eine Trägerhülse 19 eingesetzt, auf welcher das Gehäuse 17 befestigt ist. Die Trägerhülse 19 macht zwar die laterale Bewegung der Antriebswelle 32 beim Verdrehen der Exzenterbuchse 20 zwangsweise mit, jedoch ist sie in der Exzenterbuchse 20 drehbar gelagert, und sie wird durch eine entsprechende Befestigung am Gestell 16 daran gehindert, sich mit der Exzenterbuchse 20 mitzudrehen. Dementsprechend bleibt die Rotationsachse 35 der Formrolle 11 bei einem Verdrehen der Exzenterbuchse 20 unverändert.In order to prevent the housing 17 from rotating during rotation of the eccentric bushing 20 and thereby moving the rotational axis 35 of the forming roller 11 out of the working position along a conical surface, a carrier sleeve 19 is inserted into the eccentric bushing 20, on which the housing 17 is attached. Although the support sleeve 19 makes the lateral movement of the drive shaft 32 during rotation of the eccentric bush 20 forcibly with, but it is rotatably mounted in the eccentric bushing 20, and it is prevented by a corresponding attachment to the frame 16 from rotating with the eccentric bushing 20. Accordingly, the rotation axis 35 of the forming roller 11 remains unchanged upon rotation of the eccentric bushing 20.

Wie dies funktioniert, wird am besten anhand der nebeneinander angeordneten Figuren 5, 5a, 6, 6a, 7 und 7a deutlich, wobei die Figuren 5, 6 und 7 jeweils eine Teilansicht entlang des Schnittes A-A aus Figur 1 sind, während die Figuren 5a, 6a und 7a Teilausbrüche entlang des Schnittes B-B aus Figur 1 darstellen.How this works is best understood from the juxtaposed Figures 5, 5a, 6, 6a, 7 and 7a, with Figures 5, 6 and 7 each being a partial view taken along section AA of Figure 1, while Figures 5a, Figures 6a and 7a illustrate partial breakouts along section BB of Figure 1.

Wie zuvor anhand der Figuren 2 und 3 - ebenfalls einer Teilansicht entlang des Schnittes A-A und ein Teilausbruch entlang des Schnittes B-B - verdeutlicht wird, sitzt die Antriebswelle 32 drehbar in der Trägerhülse 19 und diese wiederum drehbar in der Exzenterbuchse 20, und diese ihrerseits drehbar im Gestell 16. Die Trägerhülse 19 weist eine in diesem Schnitt vollflächig zu sehende Kopfplatte auf, die mit vier Bohrungen versehen ist. In den Bohrungen sitzt jeweils ein Exzenterbolzen 21, 22, 23 und 24, dessen Exzentermaß e dasselbe Exzentermaß ist, wie dasjenige der Exzenterhülse 20.As previously shown with reference to Figures 2 and 3 - also a partial view along the section AA and a partial break along the section BB - illustrates the drive shaft 32 is rotatably mounted in the support sleeve 19 and this turn rotatably in the eccentric bushing 20, and this in turn rotatable in Frame 16. The carrier sleeve 19 has a full surface in this section to see Head plate, which is provided with four holes. In each of the holes sits an eccentric pin 21, 22, 23 and 24, whose eccentric e is the same eccentric, as that of the eccentric sleeve 20th

Wie in Figur 4 und dem als Figur 8 vergrößerten Detail Z zu sehen, sitzen die Exzenterbolzen 21, 22, 23 und 24 jeweils frei drehbar sowohl in der Kopfplatte der Trägerhülse 19 als auch in entsprechenden Bohrungen im Gestell 16, und zwar vermittels Wälzlagern 37 in diesem besonders leicht drehbar.As can be seen in FIG. 4 and the enlarged detail Z as FIG. 8, the eccentric pins 21, 22, 23 and 24 are each freely rotatable both in the top plate of the carrier sleeve 19 and in corresponding bores in the frame 16, by means of roller bearings 37 in FIG this particularly easy to turn.

Wie in den Figuren 5, 5a, 6, 6a, 7, 7a verdeutlicht wird, führt dies insgesamt dazu, dass bei einer Verdrehung der Exzenterbuchse 20 um beispielsweise plus 30 Grad (Figuren 6, 6a) oder minus 30 Grad (Figuren 7, 7a), die zu einer lateralen, achsparallelen Versetzung der Achse der Antriebswelle 32 um das Exzentermaß e führt, dazu, dass sich die frei drehbaren Exzenterbolzen 21, 22, 23, 24 in dieselbe Winkellage wie die Exzenterhülse 20 verdrehen und somit ebenfalls eine laterale Verschiebung der Trägerhülse 19 um das Exzentermaß e zulassen. Da es sich um mehr als einen Exzenterbolzen 21 handelt, ist eine Verdrehung der Trägerhülse 19, also ein Mitdrehen derselben mit der Exzenterbuchse 20, ausgeschlossen.As is illustrated in FIGS. 5, 5a, 6, 6a, 7, 7a, this leads overall to a situation in which the eccentric bush 20 is rotated by, for example, plus 30 degrees (FIGS. 6, 6a) or minus 30 degrees (FIGS. 7, 7a ), which leads to a lateral, axially parallel displacement of the axis of the drive shaft 32 by the Exzentermaß e, to the fact that the freely rotatable eccentric pin 21, 22, 23, 24 rotate in the same angular position as the eccentric sleeve 20 and thus also a lateral displacement of Carrier sleeve 19 to allow the eccentric e. Since it is more than one eccentric pin 21, a rotation of the support sleeve 19, so a co-rotation of the same with the eccentric bushing 20 is excluded.

Wie anhand der Figuren 1 und 10 klar wird - Figur 10 zeigt ein bereits profiliertes Werkstoffband 31, das zwischen den Formrollen 11 und 12 sowie der Seitenrolle 14 weiter umgeformt wird - dass es zur Anpassung an unterschiedliche Dicken des Werkstoffbandes 31 nicht ausreicht, die Formrolle 11 in y-Richtung zu verstellen. Es muss vorliegend eine synchrone Verstellung in x-Richtung hinzukommen, da die Formrolle 11 in etwa in der Winkelhalbierenden der senkrecht aufeinander stehenden Formrolle 12 und Seitenrolle 14 wirkt.
Bei anderen Winkeln muss entsprechend eine asynchrone Verstellung in x-Richtung erfolgen.As is clear from Figures 1 and 10 - Figure 10 shows an already profiled material strip 31, which is further formed between the forming rollers 11 and 12 and the side roller 14 - that it is not sufficient to adapt to different thicknesses of the material strip 31, the forming roller 11th to adjust in y-direction. In the present case, a synchronous adjustment in the x-direction must be added since the shaping roller 11 acts approximately in the bisecting line of the form roller 12 and side roller 14 which are perpendicular to one another.
For other angles, an asynchronous adjustment in the x direction must be carried out accordingly.

Über ein Gewinde 26, mit dem die Exzenterbuchse 20 an ihrer Außenfläche versehen ist, und einem auf diesem Gewinde 26 laufenden Zahnrad 27, welches sich axial nicht relativ zum Gestell 16 bewegen kann, kann durch Drehung dieses Zahnrades 27 eine axiale Verstellung der Exzenterhülse 20 und mit dieser der Trägerhülse 19, des Gehäuses 17 und letztendlich der Formrolle 11 bewirkt werden, wobei die Formrolle 11 wegen ihrer Abwinkelung nicht axial verstellt wird, sondern in x-Richtung. Die Drehung des Zahnrades 27 und somit die axiale Verstellung der Exzenterbuchse 20 erfolgt maschinell durch einen Stellantrieb 29 über ein weiteres Zahnrad 28, das mit dem Zahnrad 27 kämmt.Via a thread 26, with which the eccentric bushing 20 is provided on its outer surface, and a current on this thread 26 gear 27, which can not move axially relative to the frame 16, by rotation of this gear 27, an axial displacement of the eccentric sleeve 20 and with this the carrier sleeve 19, the housing 17 and ultimately the forming roller 11 causes the forming roller 11 is not adjusted axially because of their bending, but in the x direction. The rotation of the gear 27 and thus the axial adjustment of the eccentric bushing 20 is carried out mechanically by an actuator 29 via a further gear 28 which meshes with the gear 27.

Auch die Verdrehung der Exzenterbuchse 20 über den Schwenkhebel 25 kann mittels eines (hier nicht dargestellten) Stellantriebs erfolgen; so dass sowohl die Verstellung der Formrolle 11 in x-Richtung als auch die Verstellung der Formrolle 11 in y-Richtung mittels NC-Achsensteuerungen synchron oder asynchron erfolgen kann. Die Haltekräfte, die auf den Schwenkhebel 25 einwirken müssen, um das Rückmoment auf die Exzenterbuchse 20 von den Umformkräften an der Formrolle 11 abzufangen, sind aufgrund der Hebelwirkung, insbesondere jedoch aufgrund des Verhältnisses des kleinen Exzentermaßes e und des groß gewählten Außendurchmessers der Exzenterbuchse 20 sowie einer entsprechenden, einen gewissen Widerstand bietenden Lagerung der Exzenterbuchse 20 im Gestell 16, aufgrund deren eine Selbsthemmung der Verdrehung der Exzenterbuchse 20 eintritt, äußerst gering.Also, the rotation of the eccentric bushing 20 via the pivot lever 25 can be effected by means of an actuator (not shown here); so that both the adjustment of the forming roller 11 in the x direction and the adjustment of the forming roller 11 in the y direction by means of NC axis controls can be synchronous or asynchronous. The holding forces that must act on the pivot lever 25 to intercept the moment of return on the eccentric bush 20 of the forming forces on the forming roller 11, due to the leverage, but in particular due to the ratio of the small eccentric e and the large selected outer diameter of the eccentric bushing 20 and a corresponding, providing a certain resistance storage of the eccentric bushing 20 in the frame 16, due to which a self-locking of the rotation of the eccentric bushing 20 occurs, extremely low.

Da in einer Rollumformanlage mehrere Profiliergerüste in Linie hintereinander angeordnet sind, die alle erfindungsgemäß ausgestaltet sein können, kann eine mechanische Zwangskopplung der jeweiligen Exzenterbuchsen 20, 20' vorgesehen sein, wie Figur 9 zeigt. Denn hier ist der Schwenkhebel 25 eines ersten Profiliergerüsts 10 über ein Gestänge 30 mit dem Schwenkhebel 25' eines zweiten Profiliergerüsts 10' mechanisch verbunden. Ein einziger Stellantrieb wirkt also auf eine ganze Reihe (hier auf zwei) Profiliergerüste 10 und 10'.Since a plurality of profiling stands are arranged in line one behind the other in a roll forming installation, all of which can be designed according to the invention, a mechanical forced coupling of the respective eccentric bushings 20, 20 'can be provided, as FIG. 9 shows. For here, the pivot lever 25 of a first profiling scaffold 10 via a linkage 30 with the pivot lever 25 'of a second profiling scaffold 10' mechanically connected. A single actuator thus acts on a whole series (here on two) Profiliergerüste 10 and 10 '.
